FAQs
For safe and compliant installation, ensure the transformer is mounted in a location that provides proper clearance for access and cooling, use appropriate 70 A wiring connections, and follow Class I Division 2 guidelines. The NEMA 3R enclosure supports indoor-outdoor mounting, reducing weather-related risks. Verify that the -5% FCBN taps are set correctly for your load, and plan for secure wiring routes to minimize insulation wear and accidental contact during service.
The unit is a three-phase transformer rated at 9 kVA with a 480 V primary and 208Y/120 V secondary. It incorporates aluminum windings and a -5% tap option to better manage voltage under fluctuating loads. This configuration supports reliable control power for automation circuits, with 50/60 Hz compatibility and a design that minimizes voltage drop in typical plant lighting and instrumentation circuits.
Yes, it is suited for indoor-outdoor applications thanks to the NEMA 3R enclosure and the EPTZ encapsulation, which provides robust protection against dust, moisture, and corrosive environments. TheClass 1 Division 2 rating adds an extra layer of safety in hazardous locations. Proper installation and routine inspection of sealing, mounting hardware, and wiring terminations will support long-term reliability in harsh plant settings.
The Z48G28T09A carries UL Listed certification and is designed for Class I Division 2, Groups C and D hazardous locations. The combination of UL listing, hazardous-location classification, and a rugged NEMA 3R enclosure provides regulatory confidence for safety, maintenance planning, and supplier audits in industrial facilities handling flammable materials or gases.
The transformer’s encapsulated design and aluminum windings reduce insulation and corrosion-related maintenance, lowering total cost of ownership. With a warranty covering one year from installation or 18 months from shipment and a rugged indoor-outdoor enclosure, maintenance downtime is minimized. ROI improves through reduced panel space needs, fewer replacements due to corrosion, and dependable power for critical controls and instrumentation.
